Ask HN: When to watch classic movies with kids?

Cartoon movies have been 'quiet time' for my little one since she gave up afternoon sleeps at age 1 or so. We've basically stuck to cartoons from Dreamworks or Pixar but now she's nearly at school and can handle more 'normal' movies - she loved The Goonies the other day ;-) My question is pretty straight forward: given access to history's back catalogue, what should we watch and when? Let's set some bounds with Goonies@5 and say Aliens@12ish. Ages are indicative YMMV kind of thing. I'm more interested in getting a good steer on a great list of movies to enjoy with someone for the first time again ;-)

@5 = Goonies, Last Starfighter, Ghostbusters War Games and Indiana Jones@8 etc...
